Hi,
Idea is good..!.
Below is my coding.Let me precise explaination
Hear is my c# code where i am encoding the more than 60,000 points using
polylineEncoder class.
i am storing the encoded string value into a hidden text box and from there
passing to the javascript.
textbox name is "txtEncoded" which is mentioned down in the code.
*Point :1*
Tracking objTracking = (Tracking)arrayTrackingObjects;
PolylineEncoder encoder = new PolylineEncoder();
List<Trackpoint> trackPoints = new List<Trackpoint>();
Trackpoint tp;
GooglePoint gp1 = new GooglePoint();
for (int i = 0; i < objTracking.intNoofDataPoint; i++)
{
tp = new Trackpoint(objTracking.Latitude[i], objTracking.Longitude[i]);
trackPoints.Add(tp);
}
txtEncoded.Value = encoder.Encode(trackPoints).Points;
HtmlGenericControl dispval = new HtmlGenericControl();
dispval.InnerHtml = "<script language='javascript'> loadEarth(" +
objTracking.Latitude[0] + "," + objTracking.Longitude[0] + ");</script>";
Page.Controls.Add(dispval);
Point : 2
Javascript function
function loadEarth(Lati,Longi)
{
var mapdiv=document.getElementById("map");
mapdiv.style.width="830px";
mapdiv.style.height="600px";
var geocoder = new GClientGeocoder();
geocoder.setCache=null;
// Google Maps caches KML files -- use a random query string parameter set
to Date.
var url_end = "?nocache=" + (new Date()).valueOf();
var kmlFile = "http://124.123.50.236/kml/my-vacation-photos.kml";;
var map = new GMap2(document.getElementById("map"));
// mapdiv.load("from: " + fromAddress + " to: " + toAddress,{locale:"en_au",
travelMode:G_TRAVEL_MODE_WALKING});
// Add controls
map.addControl(new GLargeMapControl());
map.addControl(new GMapTypeControl());
geoxml = new GGeoXml(kmlFile);
map.addOverlay(geoxml);
var strEncod=document.getElementById('<%= txtEncoded.ClientID %>').value;
map.addControl(new GMapTypeControl());
map.addControl(new GSmallMapControl());
var marker = new GMarker(new GLatLng(Lati,Longi));
map.setCenter(new GLatLng(Lati,Longi),14);
//GEvent.addListener(marker, "click", function() {
//marker.openInfoWindowHtml("hii");});
map.addOverlay(marker);
map.setCenter(new GLatLng(Lati,Longi), 13);
map.setMapType(G_NORMAL_MAP);
var polyline = GPolyline.fromEncoded({
color: 'Green',
weight: 6,
opacity: 0.6,
points: strEncod,
levels: 'PMP',
numLevels: 18,
zoomFactor: 1
});
map.addOverlay(polyline);
}
This is what i am using.Let me now if you any doubts or you can come to
